5(5x-4)(6x+7)=0
We multiply parentheses ..
5(+30x^2+35x-24x-28)=0
We multiply parentheses
150x^2+175x-120x-140=0
We add all the numbers together, and all the variables
150x^2+55x-140=0
a = 150; b = 55; c = -140;
Δ = b2-4ac
Δ = 552-4·150·(-140)
Δ = 87025
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{87025}=295$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(55)-295}{2*150}=\frac{-350}{300} =-1+1/6 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(55)+295}{2*150}=\frac{240}{300} =4/5 $
